SN74LS258BDR

Overview

The SN74LS258BDR is a quad 2-line to 1-line data selector/multiplexer from the Texas Instruments SN74LS series. It features four independent multiplexers with three-state outputs in a 16-pin SOIC-Narrow package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 21 ns. It functions across an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent 2-to-1 multiplexers for parallel data routing
• Provides three-state outputs to facilitate bus-driven systems
• Compatible with standard TTL logic input levels

Applications

• Data selection and routing in digital circuits
• Bus-oriented transmission systems
• Parallel-to-serial conversion applications

Procurement Notes

Verify the specific suffix 'BDR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the LS logic family specifications align with the target system's power and speed requirements before finalizing procurement orders.

Selection Notes

Select this component when multiple data sources require selection onto a common bus using three-state control. Ensure the design accommodates the 4.75 V to 5.25 V supply voltage constraints and the 21 ns propagation delay characteristics inherent to the LS logic family.

Part Context

This part belongs to the SN74LS25x family of multiplexers, designed for general-purpose digital logic applications. It serves as a standard solution for managing data flow in microprocessor-based systems and industrial control interfaces requiring reliable signal switching.

Replacement Considerations

Cross-reference with SN74LS258BD for identical functionality in a different package configuration. Verify compatibility with SN74ALS258 variants if lower power consumption or faster switching speeds are required by the application.
